The present invention relates generally to transfer assemblies of the manifolding or continuous roll feed type and t the method of making the same; and, more particularly to an improved construction and method for making multiple transfer assemblies for use with high speed printers, such as tabulating machines or the like.

With the marked technological advance in business machines and methods, there has been a corresponding need for more accurate and rapid methods for processing and recording various types of informational data. One such method has been the use of multiple transfer forms of the manifolding or continuous roll feed type which usually comprise two or more record sheets between which are interleaved in inscription transfer relation one time carbon sheets which are adapted to be detached and discarded after usage. The interleaved record and carbon sheets are usually secured together along one marginal edge to provide what is generally referred to as a stub or binding margin. Frequently, this stub or binding margin is punched to provide a series of holes for engagement by feed devices having complementary control pins, such as employed with tabulating machines, during printing, or for feeding registration during subsequent usage of the form.

In use, the multiple transfer forms are generally fed directly into duplicating or transcribing machines, such as typewriters or the like, without the need for manual manipulation or further registration of the parts.

An important problem in the manufacture of such multiple transfer forms involves joining the individual parts together in interleaved inscription transfer relation, so as to be readily fed through the high speed tabulating or other such machines which utilize marginal punching. It is essential that the marginal holes do not shift out of round so that the pins of the control units do not have to re-line or rejog the record and carbon sheets into registration prior t processing through the printing unit of the tabulating machines. The extremely fast action of the machines, such as the I.B.M. 1403, Model 3, eject paper at the rate of 70 inches per second. This extremely fast action has the tendency to shake the forms apart and out of perfect hole alignment with one another which is vitally essential to use with high speed printers.

Heretofore, it has been known to join the individual parts together by various types of fasteners, such as staples, which method has presented a plurality of difficulties. In high speed printers, the staples have caught on the ribbons and stripping wires which results in jamming of the machines. Staples being thick, tend to build-up very high in one area making the packaging of the forms extremely cumbersome and difficult. In addition, stapling is usually accomplished by an independent and costly operation which is usually carried out by intricate equipment which is often troublesome from a maintenance standpoint.

Another known fastening device is commonly referred to as a finger-lock or crimplock fastening arrangement which usually involves slitting the stub to form a series of interlocking tongues which hold the parts in collocated position. Such fastening generally penetrates completely through the form, and hence, generally mutilates all the parts of the form and makes it extremely diflicult to separate the record and carbon sheets after usage. Consequently, most users detach the mutilated stub completely, thereby losing the benefit of marginal holes for subsequent operations.

Most recently, other attempts have been made to make the stub or binding margin of the continuous forms flexible enough to pass over the feeding machines and past the printers ribbons without distortion at the cross-perforation. Most successful perhaps, has been the use of what is commonly referred to as the hot melt glue" method. Such method is accomplished by applying solid lines or intermittent spots of glue to the individual parts generally by means of the extrusion type nozzle. The ditficulty with such method resides in the fact that the glue is extremely expensive, tends to appreciably slow down the operation, and adds, in most instances, considerably to the bulk of the stub or binding margin, thereby substantially reducing the number of workable parts that may be employed in a given form. The heavy build-up of glue along the margin tends to reduce the flexibility of the stub, particularly when the form is comprised of more than six parts. In addition, when such glued forms are cross-perforated in a non-dry condition, the sheets of record and carbon paper are, in many instances, permanently out of register and in a peaked condition when subsequently dried. Such peaked condition is brought about when the record (paper) sheets are glued one to the other which causes distortion to the otherwise desirable fiat continuity of the form, which results in extremely difficult processing of the form through the high speed machines.

The present invention effectively overcomes the aforementioned and other related defects and disadvantages of the prior art, and therefore, it is a principal object of the present invention to provide an improved multiple transfer form assembly, and method for making the same, which is simple and economical to produce, and which is particularly efficient for use with high speed tabulating machines or the like.

Another object of the present invention is to provide a continuous, multiple transfer form, and method of making the same, which comprises a plurality of record members and interleaved carbon members disposed in inscription transfer relationship, which members are detachably connected together by an improved fastening means that obviates the need for conventional type fastening means, such as by stapling, hot glueing or the like.

A further object of the present invention is to provide a multiple transfer form of the character described for use with high speed machines which incorporate marginal punching, wherein the fastening means includes a novel perforated fold-over construction adjacent at least one marginal edge, which holds the individual members in collocated, enveloped relationship for continuous processing through high speed machines without n1isalignment or distortion.

A further object of the present invention is to provide a novel perforated fold-over construction of the character described which provides a smooth, flexible stub; which eliminates inadvertent glueing of the record sheets together, which prevents a peaked condition of the form, and which obviates any buildup of adhesive material adjacent the stub.

Another object of the present invention is to provide a novel perforated fold-over construction of the character described wherein the stub is provided with openings for engagement with control pins of complementary feed devices, and which maintains the holes in constant registered alignment without the need to realign or re-jog the members into position during processing through high speed tabulating machines.

Another object of the present invention is to provide a multiple transfer form which incorporates the novel perforated fold-over construction of the character described, wherein the stub includes a locking means which prevents shifting movement of the record and carbon members, and which enables separation of the members without multilation.

Another object of the present invention is to provide a multiple transfer assembly of the character described in which the record members are detachably connected to the stub for ready separation therefrom,

A still further object of the present invention is to provide a continuous, multiple transfer form and method of making the same which includes a plurality of multiple snap-out form sets detachably connected together for independent usage thereof.

Still another object of the present invention is to provide a multiple transfer form of the character described which incorporates one time transfer members interleaved in inscription transfer relationship between the record members which may be quickly and easily separated from the stub without damage thereto, and in which the aforementioned perforated fold-over construction enables the stub to be utilized as a strengthener in permanently binding and storing the record members, such as by means of a post binder or the like.

Other objects and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings wherein;

FIG. 6 is a perspective view illustrating a typical apparatus and method for making a continuous, multiple transfer form in accordance with the present invention.

Referring again to the drawings and in particular to FIGS. 1 to 4 thereof, there is illustrated a continuous, multiple transfer form, designated generally at 2, comprised of a plurality of multiple transfer sets 4 referred to generally as snap-out forms. As shown, each multiple set 4 includes a suitable number of record sheets 6, 8, 10 and 12 which are usually printed, as at 14, to provide blank forms. Interleaved in inscription transfer relation between the record sheets are a corresponding number of carbon sheets 16, 18 and 20 for duplicating the printed matter inscribed on the record sheets. Each form set 4 may preferably include any number of record sheets and a corresponding number of carbon sheets sufficient for transcribing and duplicating informational data, as desired.

In accordance with one embodiment of the present invention, the record 6, 8, 10 and 12 and carbon sheets 16, 18 and 20 are preferably all attached together adjacent one longitudinal edge to provide a stub 22 for binding the sheets together into a unitary assembly. As shown in FIG. 3, the stub 22 is provided by means of an extension or flange 24 which constitutes a continuation of the lower or bottom record sheet 12. The flange 24 is preferably folded over and around the adjacent marginal edges of the interleaved sheets and into engagement with the confronting upper surface of the upper or top record sheet 6. The flange 24 may be permanently retained in this foldover position by means of a single line of adhesive, as at 26, which may be applied by means of a suitable extrusion nozzle or the like. The adhesive may be of any suitable quick-drying and/or pressure responsive types, as are known in the art.

As shown in FIG. 1, the record sheets 6, 8, 10 and 12 are preferably, though not necessarily, of a greater transverse dimension than the interleaved carbon sheets 16, 18 and 20. Moreover, the edges of the carbon sheets opposite the stub 22 are preferably unattached and extend or terminate short of the corresponding adjacent edges of the record sheets, as shown in broken line at 27, to provide a readily accessible means for gripping the record sheets for quick and easy separation from the stub. Thus, by dimensioning the carbon sheets so that they encompass generally only the printed matter or the like to be duplicated from the record sheets, there is achieved an efficient utilization of both paper and carbon.

For purposes of registering and feeding the form through high speed tabulators or the like, the opposed longitudinal edges of the form including the stub 22 are provided with a plurality of longitudinally spaced rows of holes 28. The holes 28 preferably penetrate completely through all of the interleaved sheets to provide a suitable means for engagement by the control pins of the machine, as will hereinafter be more fully described.

By this fold-over and adhesively secured arrangement, all of the interleaved sheets are effectively retained in an enveloped relationship by means of only the top 6 and bottom 12 record sheets. This enveloped relationship maintains the sheets, and hence, the registered holes 28 in proper alignment during processing through the high speed machines. Moreover, the single-line adhesive attachment 26 of the flange 24 takes place only between the top 6 and bottom 12 record sheets (paper), thereby preventing a peaked condition of the form. In addition, the nominal usage of adhesive at the binding margin provides a smooth, flexible stub 22 which incorporates a thickness which is only very slightly greater than the aggregate thickness of all the sheets, thereby to facilitate processing through the printers without damage to the rolls or the like. Moreover, such arrangement requires the use of only one line of adhesive whereas a six part form utilizing the aforementioned conventional hot melt glue method would require for instance eleven lines of adhesive to provide the necessary securement of the parts.

As best shown in FIG. 2, the fold-over flange 24 is preferably provided with a weakened severance line 30, such as by perforating or the like, which extends longitudinally and generally intermediate the marginal edges of the interleaved sheets. By this arrangement, all of the record and carbon sheets may be detached without removal of or the necessity to discard the stub 22 simply by passing a suitable tool, such as dull blade or the like, through the weakened area. This action separates the tiny hang-ons, as in the case of perforating, whereby 5 all of the record and carbon sheets are immediately free falling and without any mutilation.

In some cases, for purposes of further securement, the stub 22 may be provided with finger or orimp lock devices, designated generally at 32, for locking all of the record and carbon sheets together in interleaved relationship with the stub 22. As best shown in FIG. 3, each such fastening device may be achieved by means of a series of spaced slits 34 which penetrate completely through all the interleaved sheets to provide flexible tongues 36. The tongues 36 are integrally attached at one end to the respective sheets and are adapted to be depressed downwardly adjacent the free end from the general plane of the form. Thus, displacement of the tongues 36 causes the same to engageably abut against the adjacent edges of the respective sheets, thereby to eifectively prevent any longitudinal and/ or lateral shifting movement of the sheets relative to one another. Moreover, such fastening arrangement provides an additional security to prevent mis-alignment of the sheets and hence, maintains proper registration of the holes 28 during processing on the high speed machines.

In some instances, it may be desirable to separate a single record and carbon sheet, as a unit from the stub 22. In such cases, each carbon sheet may be attached to a corresponding one of the record sheets by means of an adhesive, as at 38, adjacent the stub 22, as shown in FIG. 3A. In such application, care must be taken to insure that paper is not adhered to paper so as to prevent any peaked condition in the area of the stub 22 to facilitate processing through the high speed machine.

In FIG. 4 there is illustrated a plurality of the multiple transfer form sets 4 of FIG. 1 attached together to provide the continuous form strip 2 which may be conveniently stacked in a manifolded zig-zag relationship to provide a compact package assembly. In this assembly, each multiple transfer set 4 is preferably attached to an adjacent set by means of weakened transverse severance lines 40, such as by perforating, which extend completely through the record and carbon sheets to provide snapout multiple transfer forms which rifay be readily detached from the continuous strip 2 for independent usage. The individual record sheets 6, 8, l and 12 of each of the multiple transfer sets 4 may be detachably connected to its respective stub 22 by means of weakened longitudinal severance lines 4-2, such as by perforating, so that the individual record sheets of each set may be readily detached for independent tabulation of informational data.

It will be seen that the individual multiple transfer form sets 4 being joined together provide a composite elongated form strip 2 which may be readily folded transversely along the severance lines 40 into a convenient stacked arrangement. Each of the form sets may be quickly detached from the strip along the severance lines 49 while all of the record and carbon sheets may be detached by means of the fold-over stub perforation 30 or individually, as at 42, without disturbance or damage to the remaining sheets.

In FIG. 5 there is shown a cross-sectional view illustrating a modification of the multple transfer form set which includes a plurality of record sheets 6, 8, and 12 and a corresponding number of interleaved carbon sheets 16, 1d and 20, as aforesaid. In this form, however, the upper or top record sheet 6 is preferably provided with an extension or flange 44 and 45 adjacent each of its opposed longitudinal edges which constitute a continuation of the sheet. As shown, the respective oppositely disposed flanges 44 and 45 are folded-over and downwardly around the adjacent edges of the remaining sheets and into abutment against the confronting lower surface of the bottom record sheet 12. The flanges 44- and 45 are retained in this fold-over secured relationship by means of a line of adhesive 46 which is applied only between the record sheets (paper to paper) for the advantages and purposes,

as aforesaid. Preferably, the flanges 44 and 45 are each provided with the aforementioned weakened severance lines 30, such as by perforating, so that the record and carbon sheets can be readily separated from the stub without mutilation, as above described.

In FIGS. 5A and 5B there is shown another modification of the multiple transfer form set which includes the record sheets 6, 8, 10 and 12 and a corresponding number of interleaved carbon sheets 16, 18 and 20 which is generally similar to that shown in FIG. 3, except that the stub is of a pre-punched fold-over construction as compared to the fold-over and subsequently punched construction of FIG. 3. In this form, the bottom record sheet 12 (or the top record sheet 6 as in the embodiment of FIG. 5) is provided adjacent one edge with a pair of laterally spaced rows of holes 47 and 48 which are pro-punched therein, such as on single web press. Weakened severance lines are provided between the double-row of holes 47 and 48 so that the bottom record sheet 12 may be readily folded over the remaining record and carbon sheets, as aforesaid. Thus folded, the rows of holes 47 and 48 are disposed in exact aligned registration with a pre-punched row of holes 49 provided in such remaining record and transfer sheets, whereupon, a single line of adhesive 26 is preferably applied between the marginal folded over edge of the bottom record sheet 12 and the confronting surface of the next adjacent or top record sheet 6, thereby to hold such remaining record and carbon sheets in enveloped relationship in the manner as aforesaid.

In FIGS. 5C and 51) there is shown a further modification of the multiple transfer form set which includes a plurality of record sheets 6, 8, 10 and 12 and a corresponding number of interleaved carbon sheets 16, 18 and 20. In this form, the bottom record sheet 12 (or the top record sheet 6 as in the fold-down construction of FIG. 5) is provided adjacent one edge with only one row of holes 51 rather than with a double row of holes as in FIGS. 5A and 5B. Preferably, weakened severance lines 30 are provided adjacent and outwardly of the row of holes 51 so that the bottom record sheet 12 may be readily folded over the remaining record and carbon sheets. In this form, however, the fold-over terminates short of or outwardly of the aligned rows of holes 53 in the remaining record and carbon sheets, whereupon, a line of adhesive 26 is provided between the marginal edge of the folded-over bottom record sheet 12 and the confronting upper surface of the next adjacent or top record sheet 6 to retain the remaining record and carbon sheets in enveloped relationship. Moreover, in this form it will be seen that the rows of holes may be punched in all the sheets simultaneously after the fold-over operation as shown and described in connection with FIGS. 1 to 5 or the rows of holes may be pro-punched in each of the sheets prior to the fold-over operation as shown and described in connection with FIGS. 5A and 5B.

In accordance with the foregoing, it will be seen that the fold-over construction for maintaining the record and carbon sheets in interleaved and enveloped position may be achieved by folding either one or both of the marginal edges and of either the top or bottom record sheet in the manner described. Similarly, it will be noted that the top and bottom record sheets could be alternately folded adjacent the opposed diagonal marginal edges to provide such enveloped relationship for maintaining the holes 28 in proper alignment for engagement with the control pins during processing on the high speed tabulating machines.

In FIG. 6 there is illustrated one form of mechanism or apparatus, designated generally at 50, for making the continuous, multiple transfer form of the type shown for instance in FIG. 5 on a printing press. As shown, the record sheets 6, 8, 1t) and 12 are individually withdrawn from suitable supply rolls (not shown) and fed in the form of continuous strips between corresponding sets of larger 52 and smaller 54 diameter rolls. Each larger roll 52 comprises the impression roll of a printing couple (the plate roll and transfer roll having been removed as a unit) while each smaller roll 54 comprises a guide for conveying the sheets to the printing unit. Each carbon sheet 16, 18 and 20 is then withdrawn from a supply roll (not shown) and fed in the form of continuous strips over the corresponding sets of larger 52 diameter rolls so as to be moved into engagement with the associated overlying record sheets. Suitable guide rolls 56 may be provided to assist in feeding the carbon sheets into proper registered alignment with the record sheets so that all of the sheets are interleaved in a superimposed relationship for further operations.

A pair of spaced adhesive applicators 58 and 60, such as of the extrusion nozzle type, may be provided adjacent the opposed sides of the collater for applying a continuous line 26 of adhesive material to the exposed lateral extension or flanges 24 of the bottom record sheet 12. Moreover, in this form, it can be seen that the bottom record sheet 12 is preferably of a greater transverse dimension than the other remaining superimposed record and carbon sheets so that the opposed longitudinal edges provide continuous laterally projecting flanges 24 for the reception of the adhesive material 26, It will be noted that the position of the applicators 58 and 60 could easily be reversed for applying adhesive material to the underside of the flanges 24 of the top record sheet 6 to provide the fold-over construction on the opposite side of the continuous strip form.

A perforating mechanism, designated generally at 62, may be disposed below the interleaved sheets and generally forwardly of the adhesive applicators 58 and 60 for perforating the bottom record sheet 12. As shown, the mechanism 62 includes an elongated rod 64 from which extends a pair of laterally spaced arms 66 and 68 which have provided adjacent their ends with rotatable, toothed wheels 70 and 72 which are adapted to press against the material of the flanges 24 for perforating the same as the bottom record sheet 12 is passed between the associated last set of presser rolls 52 and 54.

Upon being perforated adjacent the flanges 24, the interleaved sheets are fed through a common guide mechanism 74 which automatically and simultaneously folds the flanges 24 carrying the adhesive material over into abutment against the confronting upper surface of the top record sheet 6. As shown, the guide mechanism 74 includes a lower larger diameter bar 76 and an upper smaller diameter bar 78 which are connected together in spaced, parallel relationship adjacent their ends by a pair of spaced collars 80 and 82. The collars 8t! and 82 are preferably spaced apart by an amount sufficient to correspond to the final desired transverse dimension of the form while the bars 76 and 78 are spaced apart by an amount sufficient to receive therethrough the aggregate thickness of the interleaved sheets including the fold-over flange 24. Thus by a proper correlation of the distance between the bars 76, 78 and collars 80, 82 respectively, the laterally projecting perforated flanges 24 may be uniformly and simultaneously folded-over and into secured engagement against the confronting upper surface of the top record sheet 6, whereupon, the fold-over flanges are pressed over and retained in secured relationship by means of the adhesive material 26 carried by the respective flanges.

After formation of the fold-over, the interleaved sheets are fed through a punch mechanism 84. Such mechanism preferably includes a pair of rolls 86 and 88 having a plurality of circumferentially spaced pins 90 and 92 which automatically punch the continuous rows of spaced holes 28 completely through the interleaved sheets adjacent their opposed marginal edges thereof. Such holes 28 provide a suitable engagement for the feed devices of the high speed tabulating machines, as aforesaid.

The foregoing fold-over construction may be, if desired, accomplished on a collator in which case each sheet is pre-punched with a row of holes along either and/ 0 or both marginal edges while the sheet is being printed. Such prc-punched sheets are then collated on a machine in which the sheets are moved into superimposed relationship with each other and, if desired, with sheets of carbon material in the manner similar to that illustrated in FIG. 6. Either one and/or both of the marginal edges are then folded over in the manner shown and described in connection with FIG. 6. Thereafter, the rows of pre-punched holes in the form are engaged by pins on a roll, such as 86 and 88 of FIG. 6, which then operates to hold the sheets in registration and, if desired, to assist in pulling them through the collator.

From the foregoing description and accompanying drawings, it will be seen that the multiple transfer form and the method of making the same in accordance with the present invention provides many important advantages. Paramount among these advantages resides in the novel fold-over construction which effectively retain the interleaved record and carbon sheets in an enveloped relationship with a minimal amount of adhesive material. The adhesive material is applied only between selective of the record sheets (paper to paper) which prevents any peaked condition to occur adjacent the stub of the form, and which enables the interleaved sheets to be processed through high speed tabulating machines without misalignment or damage to the marginal punching. Such arrangement obviates the need to re-align or re-jog the parts even with extremely high eject speed machines, and particularly with forms which comprise a great number of inner parts. In addition, such novel fold-over construction provides a smooth, flexible stub or binding margin which can be processed through the high speed machines without difficulty, and which enables the parts to be readily separated without mutilation. Furthermore, the stub does not add materially to the aggregate thickness of the form, but does substantially strengthen the form adjacent the marginal edge thereof so as to provide an effective reinforcement or strengthener which may be utilized for permanently storing and binding the sheets together, such as by means of a post binder or the like.

Thus, while l have illustrated herein a preferred embodiment of my invention, it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit and scope of the appended claims.
